VSWR Calculations

This VSWR calculator will calculate return loss, mismatch loss, loss in percentage and the reflection coefficient. As an added bonus, the results are modifiable and can calculate the other values. VSWR (Voltage Standing Wave Ratio) is the measure of how efficiently RF power is transmitted and is expressed as a ratio of the maximum to minimum amplitude (or the voltage or current) of the corresponding field components appearing on a line that feeds an antenna. In order to improve the VSWR, this calculator also has an extra input for adding an attenuator to improve or reduce the system VSWR.
